i don't think so. if it comes, it would be a miracle. we already got 4.2.2, 4.3 and now 4.4.2(eww! very buggy).

You never know. Sony is aware that they have pretty serious problems with the 4.4.2 wakelock/batterydrain errors and a prospective fix was seen for the Z/ZL on PTCRB. I'd say there is a chance that they will just roll the fix into 4.4.4 and push that out.

I also bet they were on a deadline to get the 4.4.2 out ASAP to the whole Zx series, as it's a baseline requirement for the simultaneously launched Smartband SWR10. Likely wanted to maximize their potential install base size.

that firmware fix is 10.5.A.0.233 which already rolled out to xperia z austria 3 carrier. it wasn't a bug fix. no firmware has been certified yet till now other than that. and it's been a month still many users haven't got 4.4.2 update yet including me!
